It appears that all of the "rumint" was true. The HTC EVO 4G smartphone and the HTC View 4G LTE tablet just had their official launches announced for Sprint. They will both appear on June 24th, although you can order the EVO 3D through a few days early on the 21st. The EVO 3D will be $200 bucks on-contract, and the View 4G will be $400 on-contract. Here's a quick breakdown of the specs for these two devices, just as a refresher:

HTC EVO 3D Android Smartphone = $200 On-Contract
